How to pass message from WPF to web

[phuocminh6464]

Hi everyone,

My WPF are loading a website by using Cefsharp and what I want is passing message from WPF to web and web is able to receive it immediately. After receiving message, website will clear localStorage. Currently, I know that using function ExecuteScriptAsync can do it but I don' t want do that.
ExecuteScriptAsync("window.localStorage.clear();");

So is there other ways to pass message to web? I want web always listen WPF and can receive message immediately after WPF sending. Something works in JS side same as JavascriptMessageReceived event in C# side

What is the problem with executing javascript exactly?

You can use a IJavascriptCallback if you like. See https://github.com/cefsharp/CefSharp/blob/cefsharp/111/CefSharp.Test/Javascript/JavascriptCallbackTests.cs for examples

How is this any different to calling a function directly? Event handlers are really just functions themselves.

You could easily implement this in your own app.
